2 / 14 page Philips Semiconductors Product specification 74LV174 Hex D-type flip-flop with reset; positive edge-trigger 2 1998 May 20 853–1964 19422 FEATURES • Wide operating voltage: 1.0 to 5.5V • Optimized for Low Voltage applications: 1.0 to 3.6V • Accepts TTL input levels between V CC = 2.7V and VCC = 3.6V • Typical V OLP (output ground bounce) t 0.8V @ VCC = 3.3V, Tamb = 25°C • Typical V OHV (output VOH undershoot) u 2V @ VCC = 3.3V, Tamb = 25°C • Output capability: standard • I CC category: MSI DESCRIPTION The 74LV174 is a low–voltage Si–gate CMOS device and is pin and function compatible with the 74HC/HCT174. The 74LV174 has six edge–triggered D–type flip–flops with individual D inputs and Q outputs. The common clock (CP) and master reset (MR) inputs load and reset (clear) all flip–flops simultaneously. The register is fully edge–triggered. The state of each D input, one set–up time prior to the LOW–to–HIGH clock transition, is transferred to the corresponding output of the flip–flop. A LOW level on the MR input forces all outputs LOW, independently of clock or data inputs. The device is useful for applications requiring true outputs only and clock and master reset inputs that are common to all storage elements.
